BACKGROUND

The majority of protein-coding genes in the human genome are composed of multiple exons (coding regions) that are separated by introns (non-coding regions). Gene expression results in a single precursor messenger RNA (pre-mRNA). The intron sequences are subsequently removed from the pre-mRNA by a process called splicing, which results in the mature messenger RNA (mRNA). By including different combinations of exons, alternative splicing gives rise to multiple mRNAs encoding distinct protein isoforms. The spliceosome, an intracellular complex of multiple proteins and ribonucleoproteins, catalyzes splicing.

Current therapeutic approaches to direct and control mRNA expression require methods such as gene therapy, genome editing, or a wide range of oligonucleotide technologies (antisense, RNAi, etc.). Gene therapy and genome editing act upstream of transcription of mRNA by influencing the DNA code and thereby changing mRNA expression. Oligonucleotides modulate the action of RNA via canonical base/base hybridization. The appeal of this approach is in the design of the basic pharmacophore of an oligonucleotide, which can be defined in a straightforward fashion by known base pairing to the target sequence subject. Each of these therapeutic modalities suffers from substantial technical, clinical, and regulatory challenges. Some limitations of oligonucleotides as therapeutics (e.g., antisense, RNAi) include unfavorable pharmacokinetics, lack of oral bioavailability, and lack of blood-brain-barrier penetration, with the latter precluding delivery to the brain or spinal cord after parenteral drug administration for the treatment of diseases (e.g., neurological diseases, brain cancers). In addition, oligonucleotides are not taken up effectively into solid tumors without a complex delivery system such as lipid nanoparticles. Further, most of the oligonucleotides taken up into cells and tissues remain in non-functional compartments (e.g., endosomes) and does not gain access to the cytosol and/or nucleus where the target is located.

Additionally, to anneal to a target, oligonucleotide therapies require access to complementary base pairs of the target. This approach assumes that pre-mRNA sequences exist as a linear strand of RNA in the cell. However, pre-mRNA is rarely linear; it has complex secondary and tertiary structure. Further, cis-acting elements (e.g., protein binding elements) and trans-acting factors (e.g., splicing complex components) can create additional two-dimensional and three-dimensional complexity (e.g., by binding to the pre-mRNA). These features can be potency- and efficacy-limiting for oligonucleotide therapies.

SUMMARY

The novel small molecule splicing modulators (SMSMs) described herein do not suffer from the limitations above, nor the structural and steric hindrances that greatly limit oligonucleotide therapies (e.g., by blocking hybridization to pre-mRNA targets). Small molecules have been essential in uncovering the mechanisms, regulations, and functions of many cellular processes, including DNA replication, transcription, and translation. While several recent reports have described screens for small molecule effectors of splicing, only a small number of constitutive or alternative splicing modulators have been identified and many of the small-molecule inhibitors lack specificity, lack selectivity, lack potency, exhibit toxicity, or are not orally available. Targeting the RNA transcriptome with small-molecule modulators represents an untapped therapeutic approach to treat a variety of RNA-mediated diseases. Accordingly, there remains a need to develop small-molecule RNA modulators useful as therapeutic agents. There is need in the art for novel modulators of splicing or splicing-dependent processes. Provided herein are small molecule splicing modulators and uses thereof that fulfill this need.

A protein or a variant thereof can be naturally occurring or recombinant.

Methods for detection and/or measurement of polypeptides in biological material are well known in the art and include, but are not limited to, Western-blotting, flow cytometry, ELISAs, RIAs, and various proteomics techniques. An exemplary method to measure or detect a polypeptide is an immunoassay, such as an ELISA. This type of protein quantitation can be based on an antibody capable of capturing a specific antigen, and a second antibody capable of detecting the captured antigen. Exemplary assays for detection and/or measurement of polypeptides are described in Harlow, E. and Lane, D. Antibodies: A Laboratory Manual, (1988), Cold Spring Harbor Laboratory Press.

Methods for detection and/or measurement of RNA in biological material are well known in the art and include, but are not limited to, Northern-blotting, RNA protection assay, RT PCR. Suitable methods are described in Molecular Cloning: A Laboratory Manual (Fourth Edition) By Michael R. Green, Joseph Sambrook, Peter MacCallum 2012, 2,028 pp, ISBN 978-1-936113-42-2.

As used here, a “small molecular weight compound” can be used interchangeably with “small molecule” or “small organic molecule”. Small molecules refer to compounds other than peptides or oligonucleotides; and typically have molecular weights of less than about 2000 Daltons, e.g., less than about 900 Daltons.

A ribonucleoprotein (RNP) refers to a nucleoprotein that contains RNA. A RNP can be a complex of a ribonucleic acid and an RNA-binding protein. Such a combination can also be referred to as a protein-RNA complex. These complexes can function in a number of biological functions that include, but are not limited to, DNA replication, gene expression, metabolism of RNA, and pre-mRNA splicing. Examples of RNPs include the ribosome, the enzyme telomerase, vault ribonucleoproteins, RNase P, heterogeneous nuclear RNPs (hnRNPs) and small nuclear RNPs (snRNPs).

Nascent RNA transcripts from protein-coding genes and mRNA processing intermediates, collectively referred to as pre-mRNA, are generally bound by proteins in the nuclei of eukaryotic cells. From the time nascent transcripts first emerge from RNA polymerase (e.g., RNA polymerase II) until mature mRNAs are transported into the cytoplasm, the RNA molecules are associated with an abundant set of splicing complex components (e.g., nuclear proteins and snRNAs). These proteins can be components of hnRNPs, which can contain heterogeneous nuclear RNA (hnRNA) (e.g., pre-mRNA and nuclear RNA complexes) of various sizes.

Splicing complex components function in splicing and/or splicing regulation. Splicing complex components can include, but are not limited to, ribonuclear proteins (RNPs), splicing proteins, small nuclear RNAs (snRNAs), small nuclear ribonucleoproteins (snRNPs), and heterogeneous nuclear ribonucleoproteins (hnRNPs). Splicing complex components include, but are not limited to, those that may be required for splicing, such as constitutive splicing, alternative splicing, regulated splicing and splicing of specific messages or groups of messages. A group of related proteins, the serine arginine rich proteins (SR proteins), can function in constitutive pre-mRNA splicing and may also regulate alternative splice-site selection in a concentration-dependent manner. SR proteins typically have a modular structure that consists of one or two RNA-recognition motifs (RRMs) and a C-terminal rich in arginine and serine residues (RS domain). Their activity in alternative splicing may be antagonized by members of the hnRNP A/B family of proteins. Splicing complex components can also include proteins that are associated with one or more snRNAs. SR proteins in human include, but are not limited to, SC35, SRp55, SRp40, SRm300, SFRS10, TASR-1, TASR-2, SF2/ASF, 9G8, SRp75, SRp30c, SRp20 and P54/SFRS11. Other splicing complex components in human that can be involved in splice site selection include, but are not limited to, U2 snRNA auxiliary factors (e.g. U2AF65, U2AF35), Urp/U2AF1-RS2, SF1/BBP, CBP80, CBP 20, SF1 and PTB/hnRNP1. hnRNP proteins in humans include, but are not limited to, A1, A2/B1, L, M, K, U, F, H, G, R, I and C₁/C₂. Human genes encoding hnRNPs include HNRNPA0, HNRNPA1, HNRNPA1L1, HNRNPA1L2, HNRNPA3, HNRNPA2B1, HNRNPAB, HNRNPB1, HNRNPC, HNRNPCL1, HNRNPD, HNRPDL, HNRNPF, HNRNPH1, HNRNPH2, HNRNPH3, HNRNPK, HNRNPL, HNRPLL, HNRNPM, HNRNPR, HNRNPU, HNRNPUL1, HNRNPUL2, HNRNPUL3, and FMR1. Splicing complex components may be stably or transiently associated with a snRNP or with a transcript.

The term “intron” refers to both the DNA sequence within a gene and the corresponding sequence in the unprocessed RNA transcript. As part of the RNA processing pathway, introns can be removed by RNA splicing either shortly after or concurrent with transcription. Introns are found in the genes of most organisms and many viruses. They can be located in a wide range of genes, including those that generate proteins, ribosomal RNA (rRNA), and transfer RNA (tRNA).

An “exon” can be any part of a gene that encodes a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing. The term “exon” refers to both the DNA sequence within a gene and to the corresponding sequence in RNA transcripts.

A “spliceosome” can be assembled from snRNAs and protein complexes. The spliceosome can remove introns from a transcribed pre-mRNA.

“Medium effective dose” (ED₅₀) is the dose at which 50% of a population expresses a specified response. “Medium lethal dose” (LD₅₀) is the dose at which 50% of a population dies. “Medium toxic dose” (TD₅₀) is the dose at which 50% of a population expresses a specified toxic effect. One particularly useful pharmacological indicator is the “therapeutic index” which is traditionally defined as the ratio of LD₅₀ to ED₅₀ or the ratio of TD₅₀ to ED₅₀. Therapeutic index provides a simple and useful indicator of the benefit versus adverse effect of a drug. Those drugs which have a high therapeutic index have a large therapeutic window, i.e., the drugs may be administered over a wider range of effective doses without incurring significant adverse events. Conversely, drugs having a small therapeutic index have a small therapeutic window (small range of effective doses without incurring significant adverse events).

The term “AUC” as used herein refers to an abbreviation for “area under the curve” in a graph of the concentration of a therapeutic agent over time in a certain part or tissue, such as blood or plasma, of a subject to whom the therapeutic agent has been administered.

Small Molecule Splicing Modulators (SMSMs)

It has now been found that compounds of this invention, and pharmaceutically acceptable compositions thereof, are effective as agents for use in treating, preventing, or ameliorating a disease or condition associated with a target RNA. The present invention provides the unexpected discovery that certain small chemical molecules can modify splicing events in pre-mRNA molecules, herein referred to as small molecule splicing modulators (SMSMs). These SMSMs can modulate specific splicing events in specific pre-mRNA molecules. These SMSMs can operate by a variety of mechanisms to modify splicing events. For example, the SMSMs of this invention can: 1) interfere with the formation and/or function and/or other properties of splicing complexes, spliceosomes, and/or their components such as hnRNPs, snRNPs, SR-proteins and other splicing factors or elements, resulting in the prevention or induction of a splicing event in a pre-mRNA molecule. As another example; 2) prevent and/or modify post-transcriptional regulation (e.g., splicing) of gene products, such as hnRNPs, snRNPs, SR-proteins and other splicing factors, which can subsequently be involved in the formation and/or function of a spliceosome or splicing complex component; 3) prevent and/or modify phosphorylation, glycosylation and/or other modifications of gene products including, but not limited to, hnRNPs, snRNPs, SR-proteins and other splicing factors, which can subsequently be involved in the formation and/or function of a spliceosome or splicing complex component; 4) bind to and/or otherwise affect specific pre-mRNA so that a specific splicing event is prevented or induced, e.g., via a mechanism that does not involve base pairing with RNA in a sequence-specific manner. The small molecules of this invention are different from and are not related to antisense or antigene oligonucleotides.

Described herein are compounds modifying splicing of gene products for use in the treatment, prevention and/or delay of progression of diseases or condiations (e.g., cancer). Described herein are compounds modifying splicing of gene products wherein the compounds induce a transcriptionally inactive variant or transcript of a gene product.

In some embodiments, an SMSM described herein, possesses one or more stereocenters and each stereocenter exists independently in either the R or S configuration. The compounds presented herein include all diastereomeric, enantiomeric, and epimeric forms as well as the appropriate mixtures thereof. The compounds and methods provided herein include all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers as well as the appropriate mixtures thereof. In certain embodiments, compounds described herein are prepared as their individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds/salts, separating the diastereomers and recovering the optically pure enantiomers. In some embodiments, resolution of enantiomers is carried out using covalent diastereomeric derivatives of the compounds described herein. In another embodiment, diastereomers are separated by separation/resolution techniques based upon differences in solubility. In other embodiments, separation of stereoisomers is performed by chromatography or by the forming diastereomeric salts and separation by recrystallization, or chromatography, or any combination thereof. Jean Jacques, Andre Collet, Samuel H. Wilen, “Enantiomers, Racemates and Resolutions”, John Wiley And Sons, Inc., 1981. In one aspect, stereoisomers are obtained by stereoselective synthesis.

In some embodiments, compounds described herein are prepared as prodrugs. A “prodrug” refers to an agent that is converted into the parent drug in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. In some embodiments, the design of a prodrug increases the effective water solubility. An example, without limitation, of a prodrug is a compound described herein, which is administered as an ester (the “prodrug”) to facilitate transmittal across a cell membrane where water solubility is detrimental to mobility but which then is metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water-solubility is beneficial. A further example of a prodrug might be a short peptide (polyaminoacid) bonded to an acid group where the peptide is metabolized to reveal the active moiety. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically active form of the compound. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the biologically, pharmaceutically or therapeutically active form of the compound.

In one aspect, prodrugs are designed to alter the metabolic stability or the transport characteristics of a drug, to mask side effects or toxicity, to improve the flavor of a drug or to alter other characteristics or properties of a drug. By virtue of knowledge of pharmacokinetic, pharmacodynamic processes and drug metabolism in vivo, once a pharmaceutically active compound is known, the design of prodrugs of the compound is possible. (see, for example, Nogrady (1985) Medicinal Chemistry A Biochemical Approach, Oxford University Press, New York, pages 388-392; Silverman (1992), The Organic Chemistry of Drug Design and Drug Action, Academic Press, Inc., San Diego, pages 352-401, Rooseboom et al., Pharmacological Reviews, 56:53-102, 2004; Aesop Cho, “Recent Advances in Oral Prodrug Discovery”, Annual Reports in Medicinal Chemistry, Vol. 41, 395-407, 2006; T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems, Vol. 14 of the A.C.S. Symposium Series).

In some cases, some of the herein-described compounds may be a prodrug for another derivative or active compound.

In some embodiments, sites on the aromatic ring portion of compounds described herein are susceptible to various metabolic reactions Therefore incorporation of appropriate substituents on the aromatic ring structures will reduce, minimize or eliminate this metabolic pathway. In specific embodiments, the appropriate substituent to decrease or eliminate the susceptibility of the aromatic ring to metabolic reactions is, by way of example only, a halogen, or an alkyl group.

In another embodiment, the compounds described herein are labeled isotopically (e.g. with a radioisotope) or by another other means, including, but not limited to, the use of chromophores or fluorescent moieties, bioluminescent labels, or chemiluminescent labels.

Compounds described herein include isotopically-labeled compounds, which are identical to those recited in the various formulae and structures presented herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into the present compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, sulfur, fluorine and chlorine, such as, for example, ²H, ₃h, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³⁵S, ¹⁸F, ³ ₆cl. In one aspect, isotopically-labeled compounds described herein, for example those into which radioactive isotopes such as ³H and ¹⁴C are incorporated, are useful in drug and/or substrate tissue distribution assays. In one aspect, substitution with isotopes such as deuterium affords certain therapeutic advantages resulting from greater metabolic stability, such as, for example, increased in vivo half-life or reduced dosage requirements.

In additional or further embodiments, the compounds described herein are metabolized upon administration to an organism in need to produce a metabolite that is then used to produce a desired effect, including a desired therapeutic effect.

Compounds described herein may be formed as, and/or used as, pharmaceutically acceptable salts.

Splicing

Extensive posttranscriptional processing occurs before eukaryotic pre-mRNA matures and exits from the nucleus to the cytoplasm, including the addition of a 7-methylguanosine cap at the 5′ end, the cleavage and addition of a poly-A tail at the 3′ end as well as the removal of intervening sequences or introns by the spliceosome. The vast majority of higher eukaryotic genes contain multiple introns that are spliced out with high precision and fidelity in order to maintain the reading frame of the exons. Splicing of pre-mRNA can utilize the recognition of short consensus sequences at the boundaries and within introns and exons by an array of small nuclear ribonucleoprotein (snRNP) complexes (e.g., snRNPs U1, U2, U4, U5, U6, U11, U12m U4atc and U6 atc) and a large number of proteins, including spliceosomal proteins and positively as well as negatively acting splicing modulators.

Serine-arginine-rich (SR)-domain-containing proteins generally serve to promote constitutive splicing. They can also modulate alternative splicing by binding to intronic or exonic splicing enhancer (ISE) or ESE, respectively) sequences. Other pre-mRNA binding proteins, such as hnRNPs, regulate splicing by binding to intronic or exonic splicing suppressor (ISS or ESS, respectively) sequences and can also act as general splicing modulators. The SR protein family is a class of at least 10 proteins that have a characteristic serine/arginine rich domain in addition to an RNA-binding. SR proteins are generally thought to enhance splicing by simultaneously binding to U170K, a core component of the U1 snRNP, at the 5′ splice site, and the U2AF35 at the 3′ splice site, thus bridging the two ends of the intron. While this particular function of SR proteins seems to be redundant, as any individual SR protein can commit a pre-mRNA for constitutive splicing, the role of the various SR proteins in alternative splicing of specific pre-mRNAs is distinct due in part to their ability to recognize and bind to unique consensus sequences. Phosphorylation of the RS domain of SR proteins can lead to the regulation of their protein interactions, RNA binding, localization, trafficking, and role in alternative splicing. Several cellular kinases that phosphorylate SR proteins have been identified, including SR protein Kinase (SRPKs), Cdc2-like kinases (Clks), pre-mRNA processing mutant 4 (PRP4), and topoisomerase I. Optimal phosphorylation of SR proteins may be required for proper functioning as both hypo- and hyperphosphorylation of the RS domains may be detrimental to their role in constitutive and alternative splicing.

In higher eukaryotes, the vast majority of genes contain one or more introns, which creates a situation in which the exons are spliced together to generate mature mRNA and microRNA (miRNA). In the host nucleus, pre-mRNA splicing is the mechanism by which introns are removed from a pre-mRNA and the exons are ligated together to generate mature mRNAs and pre-miRNA that is then exported to the cytoplasm for translation into the polypeptide gene product. Splicing of pre-mRNA can occur in cis, where two exons derive from two adjacent cotranscribed sequences, or in trans, when the two exons come from different pre-mRNA transcripts. The ratio of the different protein products (isoforms) may be due to the frequency of alternative splicing events within a pre-mRNA that leads to different amounts of distinct splice variants. In some embodiments, alternative splicing of a pre-mRNA may lead to 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 protein isoforms being expressed.

Aberrations in splicing are thought to be the cause of roughly half of all inherited diseases. Aberrant splicing due to mutations in consensus sequences involved in exon-intron boundary recognition is responsible for up to 15% of inherited diseases. In addition, defects in the splicing machinery itself due to the loss or gain of function of splicing factors and modulators are causes of a wide range of human ailments from cancer to neurodegenerative diseases. Both constitutive and alternative splicing are subject to regulation by upstream signaling pathways. This regulation can be essential during development, in tissue specific expression of certain isoforms, during the cell cycle and in response to extrinsic signaling molecules.

Alternative splicing allows for a single gene to express different isoforms of mRNA, thus playing a major role in contributing to the cellular complexity in higher eukaryotes without the need to expand the genome. Splicing can also be subject to regulation by upstream signaling pathways. For example, an upstream signaling pathway may modulate alternative splicing and increase or decrease expression levels of different isoforms of mRNA.

Alternative splicing events are highly regulated by numerous splicing factors in a tissue type-, developmental stage-, and signal-dependent manner. Furthermore, non-mutation based causes of splicing defects and defects in the splicing machinery itself, e.g., due to the loss/gain of function of splicing factors or their relative stoichiometry, cause of a wide range of human ailments, ranging from cancer to neurodegenerative diseases. In many diseases the disease state is caused by an alteration of the ratio of different isoforms of two or more proteins expressed from a gene. In some embodiments, the alteration in the ratio of the protein products is due to changes in the frequency of alternative splicing events within a pre-mRNA, leading to changes in the ratio of splice variants produced. In some embodiments, alternative splicing of a pre-mRNA may lead to 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 protein isoforms being expressed. In some embodiments, a change in the splice variant ratio is caused by genetic mutation.

In eukaryotes, the vast majority of splicing processes are catalyzed by the spliceosome, an RNA-protein complex that occurs in unique steps and may comprise a subset of several hundred different proteins, in addition to five spliceosomal snRNAs. These factors are responsible for the accurate positioning of the spliceosome on the 5′ and 3′ splice site sequences. The reason why so many factors are needed reflects the observation that exon recognition can be affected by many pre-mRNA features such as exon length, sequence recognition, the presence of enhancer and silencer elements, the strength of upstream splicing signals, the promoter architecture, and the rate of RNA processivity, secondary and tertiary RNA structure.

All mammalian diseases are ultimately mediated by the transcriptome. Insofar as messenger mRNA (mRNA) is part of the transcriptome, and all protein expression derives from mRNAs, there is the potential to intervene in protein-mediated diseases by modulating the expression of the relevant protein and by, in turn, modulating the translation of the corresponding upstream mRNA. But mRNA is only a small portion of the transcriptome: other transcribed RNAs also regulate cellular biology either directly by the structure and function of RNA structures (e.g., ribonucleoproteins) as well as via protein expression and action, including (but not limited to) microRNA (miRNA), long noncoding RNA (lncRNA), long intergenic noncoding RNA (lincRNA), small nucleolar RNA (snoRNA), small nuclear RNA (snRNA), small Cajal body-specific RNA (scaRNA), piwi-interacting RNA (piRNA), competing endogenous (ceRNA), and pseudo-genes. Drugs that intervene at this level have the potential of modulating any and all cellular processes. Existing therapeutic modalities such as antisense RNA or siRNA, in most cases, have yet to overcome significant challenges such as drug delivery, absorption, distribution to target organs, pharmacokinetics, and cell penetration. In contrast, small molecules have a long history of successfully surmounting these barriers and these qualities, which make them suitable as drugs, are readily optimized through a series of analogues to overcome such challenges. In sharp contrast, the application of small molecules as ligands for RNA that yield therapeutic benefit has received little to no attention from the drug discovery community.

DNA sequences in the chromosome are transcribed into pre-mRNAs which contain coding regions (exons) and generally also contain intervening non-coding regions (introns). Introns are removed from pre-mRNAs through splicing. Pre-mRNA splicing proceeds by a two-step mechanism. In the first step, the 5′ splice site is cleaved, resulting in a “free” 5′ exon and a lariat intermediate. In the second step, the 5′ exon is ligated to the 3′ exon with release of the intron as the lariat product. These steps are catalyzed in a complex of small nuclear ribonucleoproteins and proteins called the spliceosome.

In most cases, the splicing reaction occurs within the same pre-mRNA molecule, which is termed cis-splicing. Splicing between two independently transcribed pre-mRNAs is termed trans-splicing.

Introns are portions of eukaryotic DNA, which intervene between the coding portions, or “exons,” of that DNA. Introns and exons are transcribed into RNA termed “primary transcript, precursor to mRNA” (or “pre-mRNA”). Introns can be removed from the pre-mRNA so that the native protein encoded by the exons can be produced (the term “native protein” as used herein refers to naturally occurring, wild type, or functional protein). The removal of introns from pre-mRNA and subsequent joining of the exons is carried out in the splicing process.

The splicing process is a series of reactions, which are carried out on RNA after transcription but before translation and which are mediated by splicing factors. Thus, a “pre-mRNA” can be an RNA that contains both exons and intron(s), and a mature mRNA (“mRNA”) can be an RNA in which the intron(s) have been removed and the exons joined together sequentially so that the protein may be translated therefrom by the ribosomes.

Introns can be defined by a set of “splice elements” that are part of the splicing machinery and may be required for splicing and which are relatively short, conserved RNA segments that bind the various splicing factors, which carry out the splicing reactions. Thus, each intron is defined by a 5′ splice site, a 3′ splice site, and a branch point situated there between. Splice elements also comprise exon splicing enhancers and silencers, situated in exons, and intron splicing enhancers and silencers situated in introns at a distance from the splice sites and branch points. In addition to splice site and branch points these elements control alternative aberrant and constitutive splicing.

Initial RNA transcripts (pre-mRNA) of most eukaryotic genes are retained in the nucleus until non-coding intron sequences are removed by the spliceosome to produce mature messenger RNA (mRNA). The splicing that occurs can vary, so the synthesis of alternative protein products from the same primary transcript can be affected by tissue-specific or developmental signals. A significant fraction of human genetic diseases, including a number of cancers, are believed to result from deviations in the normal pattern of pre-mRNA splicing. The spliceosome is a complex comprising ribonucleoprotein (snRNP) particles composed of small nuclear RNAs and proteins. snRNA components of the spliceosome can promote the two transesterification reactions of splicing.

Two unique spliceosomes coexist in most eukaryotes: the U2-dependent spliceosome, which catalyzes the removal of U2-type introns, and the less abundant U12-dependent spliceosome, which is present in only a subset of eukaryotes and splices the rare U12-type class of introns. The U2-dependent spliceosome is assembled from the U1, U2, U5, and U4/U6 snRNPs and numerous non-snRNP proteins. The U2 snRNP is recruited with two weakly bound protein subunits, SF3a and SF3b, during the first ATP-dependent step in spliceosome assembly. SF3b is composed of seven conserved proteins, including PHF5c, SF3b155, SF3b145, SF3b130, SF3b49, SF3b14a, and SF3b10.

Splicing or RNA splicing typically refers to the editing of the nascent precursor messenger RNA (pre-mRNA) transcript into a mature messenger RNA (mRNA). Splicing is a biochemical process which includes the removal of introns followed by exon ligation. Sequential transesterification reactions are initiated by a nucleophilic attack of the 5′ splice site (5′ss) by the branch adenosine (branch point; BP) in the downstream intron resulting in the formation of an intron lariat intermediate with a 2′, 5′-phosphodiester linkage. This is followed by a 5′ss-mediated attack on the 3′ splice site (3′ss), leading to the removal of the intron lariat and the formation of the spliced RNA product.

Splicing can be regulated by various cis-acting elements and trans-acting factors. Cis-acting elements are sequences of the mRNA and can include core consensus sequences and other regulatory elements. Core consensus sequences typically can refer to conserved RNA sequence motifs, including the 5′ss, 3′ss, polypyrimidine tract and BP region, which can function for spliceosome recruitment. BP refers to a partially conserved sequence of pre-mRNA, generally less than 50 nucleotides upstream of the 3′ss. BP reacts with the 5′ss during the first step of the splicing reaction. Other regulatory cis-acting elements can include exonic splicing enhancer (ESE), exonic splicing silencer (ESS), intronic splicing enhancer (ISE), and intronic splicing silencer (ISS). Trans-acting factors can be proteins or ribonucleoproteins which bind to cis-acting elements.

Splice site identification and regulated splicing can be accomplished principally by two dynamic macromolecular machines, the major (U2-dependent) and minor (U12-dependent) spliceosomes. Each spliceosome contains five snRNPs: U1, U2, U4, U5 and U6 snRNPs for the major spliceosome (which processes ˜95.5% of all introns); and U11, U12, U4atac, U5 and U₆ atac snRNPs for the minor spliceosome. Spliceosome recognition of consensus sequence elements at the 5′ss, 3′ss and BP sites is one of the steps in the splicing pathway, and can be modulated by ESEs, ISEs, ESSs, and ISSs, which can be recognized by auxiliary splicing factors, including SR proteins and hnRNPs. Polypyrimidine tract-binding protein (PTBP) can bind to the polypyrimidine tract of introns and may promote RNA looping.

Alternative splicing is a mechanism by which a single gene may eventually give rise to several different proteins. Alternative splicing can be accomplished by the concerted action of a variety of different proteins, termed “alternative splicing regulatory proteins,” that associate with the pre-mRNA, and cause distinct alternative exons to be included in the mature mRNA. These alternative forms of the gene's transcript can give rise to distinct isoforms of the specified protein. Sequences in pre-mRNA molecules that can bind to alternative splicing regulatory proteins can be found in introns or exons, including, but not limited to, ISS, ISE, ESS, ESE, and polypyrimidine tract. Many mutations can alter splicing patterns. For example, mutations can be cis-acting elements, and can be located in core consensus sequences (e.g. 5′ss, 3′ss and BP) or the regulatory elements that modulate spliceosome recruitment, including ESE, ESS, ISE, and ISS.

A cryptic splice site, for example, a cryptic 5′ss and a cryptic 3′ss, can refer to a splice site that is not normally recognized by the spliceosome and therefore are in the dormant state. Cryptic splice site can be recognized or activated, for example, by mutations in cis-acting elements or trans-acting factors, or structural configurations, such as bulges.

Provided herein are small molecule splicing modulators (SMSMs) that modulate splicing of a target polynucleotide. In some embodiments, the SMSMs bind and modulate target RNA. In some embodiments, provided herein is a library of SMSMs that bind and modulate one or more target RNAs. In some embodiments, the target RNA is mRNA. In some embodiments, the target RNA is mRNA a noncoding RNA. In some embodiments, the target RNA is a pre-mRNA. In some embodiments, the target RNA is hnRNA. In some embodiments, the small molecules modulate splicing of the target RNA. In some embodiments, a small molecule provided herein modulates splicing at a sequence of the target RNA. In some embodiments, a small molecule provided herein modulates splicing at a cryptic splice site sequence of the target RNA. In some embodiments, a small molecule provided herein binds to a target RNA. In some embodiments, a small molecule provided herein binds to a splicing complex component. In some embodiments, a small molecule provided herein binds to a target RNA and a splicing complex component.

Thus, provided herein are methods of preventing or inducing a splicing event in a pre-mRNA molecule, comprising contacting the pre-mRNA molecule and/or other elements of the splicing machinery (e.g., within a cell) with a compound provided herein to prevent or induce the splicing event in the pre-mRNA molecule. The splicing event that is prevented or induced can be, e.g., an aberrant splicing event, a constitutive splicing event or an alternate splicing event.

Further provided herein is a method of identifying a compound capable of preventing or inducing a splicing event in a pre-mRNA molecule, comprising contacting the compound with splicing elements and/or factors involved in alternative, aberrant and/or constitutive splicing as described herein (e.g., within cells) under conditions whereby a positive (prevention or induction of splicing) or negative (no prevention or induction of splicing) effect is produced and detected and identifying a compound that produces a positive effect as a compound capable of preventing or inducing a splicing event.

In some embodiments, a small molecule compound described herein in a pharmaceutically acceptable carrier prevents or induces an alternative or aberrant splicing event in a pre-mRNA molecule. As noted above, the small molecule compounds provided herein are not antisense or antigene oligonucleotides. Table 1A, Table 1B and Table 1C show the chemical structure and name of exemplary compounds and is not intended to be all-inclusive.

In some embodiments, provided herein is a method of upregulating expression of a native protein in a cell containing a DNA encoding the native protein, wherein the DNA contains a mutation or no mutation that causes downregulation of the native protein by aberrant and/or alternate splicing thereof. For example, the DNA can encode a pre-mRNA that has a mutation or an aberrant secondary or tertiary structure that causes downregulation of one or more isoforms of a protein. The method can comprise introducing into the cell a small molecule provided herein that prevents an aberrant splicing event, whereby the native intron is removed by correct splicing and the native protein is produced by the cell. In some embodiments, a method comprises introducing into a cell a small molecule provided herein that modulates an alternate splicing event to produce a protein that has a different function than the protein that would be produced without modulation of alternate splicing.

In some embodiments, provided herein is a method of downregulating expression of a native protein in a cell containing a DNA encoding the native protein, wherein the DNA contains a mutation or no mutation that causes upregulation of the native protein by aberrant and/or alternate splicing thereof. For example, the DNA can encode a pre-mRNA that has a mutation or an aberrant secondary or tertiary structure that causes upregulation of one or more isoforms of a protein. The method can comprise introducing into the cell a small molecule provided herein that prevents an aberrant splicing event, whereby the native intron is removed by correct splicing and the native protein is produced by the cell. In some embodiments, a method comprises introducing into a cell a small molecule provided herein that modulates an alternate splicing event to produce a protein that has a different function than the protein that would be produced without modulation of alternate splicing. For example, a method can comprise preventing aberrant splicing in a pre-mRNA molecule containing a mutation or an aberrant secondary or tertiary structure and/or preventing an alternative splicing event. When present in the pre-mRNA, the mutation or aberrant secondary or tertiary structure can cause a pre-mRNA to splice incorrectly and produce an aberrant mRNA or mRNA fragment different from the mRNA ordinarily resulting from a pre-mRNA without the mutation or aberrant secondary or tertiary structure. For example, s pre-mRNA molecule can contain: (i) a first set of splice elements defining a native intron which can be removed by splicing when the mutation or aberrant secondary or tertiary structure is absent to produce a first mRNA molecule encoding a native protein, and (ii) a second set of splice elements induced by the mutation or aberrant secondary or tertiary structure which defines an aberrant intron different from the native intron, which aberrant intron is removed by splicing when the mutation or aberrant secondary or tertiary structure is present to produce an aberrant second mRNA molecule different from the first mRNA molecule. The method can comprise contacting the pre-mRNA molecule and/or other factors and/or elements of the splicing machinery as described herein (e.g., within a cell) with a compound described herein to prevent or promote an aberrant splicing event in a pre-mRNA molecule, whereby the native intron is removed by correct splicing and native protein production is increased in the cell.

Also provided herein is a method of upregulating expression of a RNA that would otherwise be downregulated by modulating an alternative splicing event in the RNA. The method can comprise contacting a pre-mRNA molecule and/or other elements and/or factors of the splicing machinery with a compound described herein to modulate alternate splicing events, whereby a native splicing event is inhibited and an alternate splicing event is promoted that upregulates expression of a RNA that is otherwise downregulated when under the control of the native splicing event.

Also provided herein is a method of downregulating expression of a RNA that would otherwise be upregulated by modulating an alternative splicing event in the RNA. The method can comprise contacting a pre-mRNA molecule and/or other elements and/or factors of the splicing machinery with a compound described herein to modulate alternate splicing events, whereby a native splicing event is inhibited and an alternate splicing event is promoted that downregulates expression of a RNA that is otherwise upregulated when under the control of the native splicing event.

The methods, compounds and compositions described herein have a variety of uses. For example, they are useful in any process where it is desired to have a means for downregulating expression of a RNA to be expressed until a certain time, after which it is desired to upregulate RNA expression. For such use, the RNA to be expressed may be any RNA encoding a protein to be produced so long as the gene contains a native intron. The RNA may be mutated by any suitable means, such as site-specific mutagenesis (see, T. Kunkel, U.S. Pat. No. 4,873,192) to deliberately create an aberrant second set of splice elements which define an aberrant intron which substantially downregulates expression of the gene. A sequence encoding the RNA may be inserted into a suitable expression vector and the expression vector inserted into a host cell (e.g., a eukaryotic cell such as a yeast, insect, or mammalian cell (e.g., human, rat)) by standard recombinant techniques. The host cell can then be grown in culture by standard techniques. When it is desired to upregulate expression of the mutated gene, a suitable compound of the present invention, in a suitable formulation, can be added to the culture medium so that expression of the gene is upregulated.

Also provided herein is a method of altering the ratio of splice variants produced from a gene. The method can comprise contacting a pre-mRNA molecule and/or other elements and/or factors of the splicing machinery with a compound or compounds described herein to modulate alternative splicing events. The compound or compounds of this invention can be used to act upon 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 alternative splicing events that may occur within a pre-mRNA. In some embodiments, a first splice variant may be downregulated or inhibited and/or a second splice variant may be upregulated, resulting in an altered ratio of splice variants of the two or more RNA. In some embodiments, a first splice variant may be upregulated while a second splice variant may be unaffected, thereby altering the ratio of the RNA. In some embodiments, a first splice variant may be downregulated while a second splicing event may be unaffected thereby altering the ratio of the RNA.

The methods, compounds and formulations described herein are also useful as in vitro or in vivo tools to examine and modulate splicing events in human or animal RNAs encoded by genes, e.g., those developmentally and/or tissue regulated (e.g., alternate splicing events).

The formulations may conveniently be presented in unit dosage form and may be prepared by any of the methods well known in the art. The most suitable route of administration in any given case may depend upon the subject, the nature and severity of the condition being treated, and the particular active compound, which is being used, as would be readily determined by one of skill in the art.

Also provided herein are methods for the use of a compound described herein having the characteristics set forth above for the preparation of a medicament for upregulating or downregulating RNA expression in a patient having a disorder associated with aberrant or alternate splicing of a pre-mRNA molecule, as discussed above.

The present inventors identify herein low molecular weight compounds (sometimes referred to herein as small molecules, which block mRNA splicing and/or enhance (facilitate, augment) mRNA splicing. The splicing that can be regulated by the methods described herein include alternative splicing, e.g., exon skipping, intron retention, pseudoexons skipping, exon exclusion, partial intron exclusion and others. Depending on factors such as the splicing sequence and the RNA (or gene encoding the RNA) or exon involved, modulation of splicing can be accomplished in the presence of, or in the absence of, antisense oligonucleotides (AOs) that are specific for splicing sequences of interest. In some embodiments, a small molecule and an AO act synergistically.

A number of diseases are associated with expression of an aberrant gene product (e.g., an RNA transcript or protein) of a gene. For example, aberrant amounts of a RNA transcript may lead to disease due to corresponding changes in protein expression. Changes in the amount of a particular RNA transcript may be the result of several factors. First, changes in the amount of RNA transcripts may be due to an aberrant level of transcription of a particular gene, such as by the perturbation of a transcription factor or a portion of the transcription process, resulting in a change in the expression level of a particular RNA transcript. Second, changes in the splicing of particular RNA transcripts, such as by perturbation of a particular splicing process or mutations in the gene that lead to modified splicing can change the levels of a particular RNA transcript. Changes to the stability of a particular RNA transcript or to components that maintain RNA transcript stability, such as the process of poly-A tail incorporation or an effect on certain factors or proteins that bind to and stabilize RNA transcripts, may lead to changes in the levels of a particular RNA transcript. The level of translation of particular RNA transcripts can also affect the amount of those transcripts, affecting or upregulating RNA transcript decay processes. Finally, aberrant RNA transport or RNA sequestration may also lead to changes in functional levels of RNA transcripts, and may have an effect on the stability, further processing, or translation of the RNA transcripts.

In some embodiments, provided herein are methods for modulating the amount of one, two, three or more RNA transcripts encoded by a pre-mRNA, comprising contacting a cell with an SMSM compound or a pharmaceutically acceptable salt thereof.

In some embodiments, provided herein are methods of treating a disease or condition in a subject in need thereof by increasing the expression of a target protein or functional RNA by cells of the subject, wherein the cells have a mutation that causes, e.g., exon skipping or intron inclusion, or a portion thereof, of pre-mRNA, wherein the pre-mRNA encodes the target protein or functional RNA. The method can comprise contacting cells of a subject with an SMSM compound or a pharmaceutically acceptable salt thereof that targets the pre-mRNA encoding the target protein or functional RNA or splicing complex component, whereby splicing of an exon from a pre-mRNA encoding a target protein or functional RNA is prevented or inhibited, thereby increasing a level of mRNA encoding the target protein or functional RNA, and increasing the expression of the target protein or functional RNA in the cells of the subject.

In some embodiments, the target protein or the functional RNA is a compensating protein or a compensating functional RNA that functionally augments or replaces a target protein or functional RNA that is deficient in amount or activity in the subject. In some embodiments, the cells are in or from a subject having a condition caused by a deficient amount or activity of the protein. In some embodiments, the deficient amount of the target protein is caused by haploinsufficiency of the target protein, wherein the subject has a first allele encoding a functional target protein, and a second allele from which the target protein is not produced, or a second allele encoding a nonfunctional target protein, and wherein an SMSM compound or a pharmaceutically acceptable salt thereof binds to a targeted portion of a pre-mRNA transcribed from the first allele.

In some embodiments, binding of an SMSM compound or a pharmaceutically acceptable salt thereof to pre-mRNA prevents splicing out of one or more exons and/or introns and/or proteins thereof, from the population of pre-mRNAs to produce mRNA encoding the target protein or functional RNA. In some embodiments, the cell comprises a population of pre-mRNAs transcribed from the gene encoding the target protein or functional RNA, wherein the population of pre-mRNAs comprises a mutation that causes the splicing out of one or more exons, and wherein an SMSM compound or a pharmaceutically acceptable salt thereof binds to the mutation that causes the splicing out of the one or more exons in the population of pre-mRNAs. In some embodiments, the binding of an SMSM compound or a pharmaceutically acceptable salt thereof to the mutation that causes the splicing out of the one or more exons prevents splicing out of the one or more exons from the population of pre-mRNAs to produce mRNA encoding the target protein or functional RNA. In some embodiments, the condition is a disease or disorder. In some embodiments, the method further comprises assessing protein expression. In some embodiments, an SMSM compound or a pharmaceutically acceptable salt thereof binds to a targeted portion of a pre-mRNA.

In some embodiments, the binding of an SMSM compound or a pharmaceutically acceptable salt thereof catalyzes the inclusion of a missing exon or removal of an undesired retained intron or portions thereof, resulting in healthy mRNA and proteins. In some embodiments, the binding of an SMSM compound or a pharmaceutically acceptable salt thereof has minimal to no effect on non-diseased cells.

In some embodiments, an SMSM kills cells at an IC₅₀ of less than 50 nM. In some embodiments, the cells are primary cells. In some embodiments, an SMSM kills the cells at an IC₅₀ of less than 48 nM, 45 nM, 40 nM, 35 nM, 30 nM, 25 nM, 20 nM, 15 nM, 10 nM, 5 nM, 3 nM, or 1 nM.

SMSM Targets

Aberrant splicing of mRNA, such as pre-mRNA, can result in a defective protein and can cause a disease or a disorder in a subject. The compositions and methods described herein can reduce this aberrant splicing of mRNA, such as pre-mRNA, and treat a disease or a disorder caused by this aberrant splicing.

Diseases associated with changes to RNA transcript amount are often treated with a focus on the aberrant protein expression. However, if the processes responsible for the aberrant changes in RNA levels, such as components of the splicing process or associated transcription factors or associated stability factors, could be targeted by treatment with a small molecule, it would be possible to restore protein expression levels such that the unwanted effects of the expression of aberrant levels of RNA transcripts or associated proteins. Therefore, there is a need for methods of modulating the amount of RNA transcripts encoded by certain genes as a way to prevent or treat diseases associated with aberrant expression of the RNA transcripts or associated proteins.

Structural Targets

Mutations and/or aberrant secondary or tertiary RNA structures in cis-acting elements can induce three-dimensional structural change in pre-mRNA. Mutations and/or aberrant secondary RNA structures in cis-acting elements can induce three-dimensional structural change in pre-mRNA when the pre-mRNA is, for example, bound to at least one snRNA, or at least one snRNP, or at least one other auxiliary splicing factor. For example, non-canonical base pairing of a non-canonical splice site sequence to a snRNA can form a bulge. For example, a bulge can be formed when the 5′ss is bound to U1-U12 snRNA or a portion thereof. For example, a bulge can be induced to form when 5′ss containing at least one mutation is bound to U1-U12 snRNA or a portion thereof. For example, a bulge can be formed when the cryptic 5′ss is bound to U1-U12 snRNA or a portion thereof. For example, a bulge can be induced to form when cryptic 5′ss containing at least one mutation is bound to U1-U12 snRNA or a portion thereof. For example, a bulge can be formed when the 3′ss is bound to U2 snRNA or a portion thereof. For example, a bulge can be induced to form when the 3′ss is bound to U2 snRNA or a portion thereof. For example, a bulge can be formed when the cryptic 3′ss is bound to U2 snRNA or a portion thereof. For example, a bulge can be induced to form when the cryptic 3′ss is bound to U2 snRNA or a portion thereof. The protein components of U1 and U2 may or may not present to form the bulge. Exemplary 5′ splice site mutations and/or with aberrant secondary and/or tertiary structures that can induce a bulge structure are shown in Table 2A, Table 2B, Table 2C and Table 2D. A polynucleotide in the methods disclosed herein can contain any one of exemplary the 5′ splice site sequences summarized in Table 2A, Table 2B, Table 2C and Table 2D.

In some embodiments, a small molecule can bind to a bulge. In some embodiments, a bulge is naturally occurring. In some embodiments, a bulge is formed by non-canonical base-pairing between the splice site and the small nuclear RNA. For example, a bulge can be formed by non-canonical base-pairing between the 5′ss and U1-U12 snRNA. The bulge can comprise 1 nucleotide, 2 nucleotides, 3 nucleotides, 4 nucleotides, 5 nucleotides, 6 nucleotides, 7 nucleotides, 8 nucleotides, 9 nucleotides, 10 nucleotides, 11 nucleotides, 12 nucleotides, 13 nucleotides, 14 nucleotides, or 15 nucleotides. In some embodiments, 3-dimensional structural changes can be induced by a mutation without bulge formation. In some embodiments, a bulge may be formed without any mutation in a splice site. In some embodiments, a recognition portion can be formed by a mutation in any of the cis-acting elements. In some embodiments, a small molecule can bind to a recognition portion that is induced by a mutation. In some embodiments, a mutation and/or aberrant secondary or tertiary RNA structure at an authentic 5′ splice site can result in splicing at a cryptic 5′ splice site. In some embodiments, a mutation and/or aberrant secondary or tertiary RNA structure can be in one of the regulatory elements including ESEs, ESSs, ISEs, and ISSs.

In some embodiments, a target of an SMSM is a pre-mRNA comprising a splice site sequence with a bulged nucleotide upstream (5′) of the splice site of the splice site sequence. In some embodiments, a target of an SMSM is a pre-mRNA comprising a splice site sequence with a bulged nucleotide at the −1 position relative to the splice site of the splice site sequence. For example, a target of an SMSM can be a pre-mRNA comprising a splice site sequence of NNN*nnnnnn, wherin N* represents a bulged nucleotide. In some embodiments, a target of an SMSM is a pre-mRNA comprising a splice site sequence with a bulged nucleotide at the −2 position relative to the splice site of the splice site sequence. For example, a target of an SMSM can be a pre-mRNA comprising a splice site sequence of NN*Nnnnnnn, wherin N* represents a bulged nucleotide. In some embodiments, a target of an SMSM is a pre-mRNA comprising a splice site sequence with a bulged nucleotide at the −3 position relative to the splice site of the splice site sequence.

Exemplary sites targeted by the SMSMs described herein include 5′ splice sites, 3′ splice sites, polypyrimidine tracts, branch sites, splicing enhancers and silencer elements. Mutations or aberrant secondary or tertiary RNA structures at hot spots can create mRNA sites or scaffold sequences that can be targeted. For example, many exons are flanked by the intronic dinucleotides GT and AG at the 5′ and 3′ splice sites, respectively. For example, mutations or aberrant secondary or tertiary RNA structures at these sites can cause, e.g., exclusion of an adjacent exon or inclusion of an adjacent intron. Many factors influence the complex pre-mRNA splicing process, including several hundred different proteins, at least five spliceosomal snRNAs, sequences on the mRNA, sequence length, enhancer and silencer elements, and strength of splicing signals. Exemplary sites targeted by the SMSMs described herein include secondary and sometimes tertiary structures of RNA. For example, exemplary sites targeted by the SMSMs described herein include a stem loop, hairpin, branch point sequence (BPS), polypyrimidine tract (PPT), 5′ splice site (5′ss) and 3′ splice site (3′ss), duplex snRNA and splice sites and trans acting protein binding to RNA. The target pre-mRNA can comprise a defective sequence, such as a sequence that produces a deficient protein, such as a protein with altered function such as enzyme activity, or expression, such as lack of expression. In some embodiments, the defective sequence impacts the structure of the RNA. In some embodiments, the defect sequence impacts recognition by snRNP.

In addition to consensus splice site sequences, structural constraints, including those resulting from mutations, can affect cis-acting sequences such as exonic/intronic splicing enhancers (ESE/ISE) or silencer elements (ESS/ISS).

In some embodiments, a mutation in native DNA and/or pre-mRNA, or an aberrant secondary or tertiary structure of RNA, creates a new splice site sequence. For example, a mutation or aberrant RNA structure may cause native regions of the RNA that are normally dormant, or play no role as splicing elements, to become activated and serve as splice sites or splice elements. Such splice sites and elements can be referred to as “cryptic”. For example, a native intron may become divided into two aberrant introns, with a new exon situated there between. For example, a mutation may create a new splice site between a native 5′ splice site and a native branch point. For example, a mutation may activate a cryptic branch point sequence between a native splice site and a native branch point. For example, a mutation may create a new splice site between a native branch point and a native splice site and may further activate a cryptic splice site and a cryptic branch point sequentially upstream from the aberrant mutated splice site.

In some embodiments, a mutation or misexpression of trans-acting proteins that regulate splicing activity may cause native regions of the RNA that are normally dormant, or play no role as splicing elements, to become activated and serve as splice sites or splice elements. For example, a mutation or misexpression of an SR protein may cause native regions of the RNA that are normally dormant, or play no role as splicing elements, to become activated and serve as splice sites or splice elements.

In some embodiments, a mutation in native DNA and/or pre-mRNA inhibits splicing at a splice site. For example, a mutation may result in a new splice site upstream from (i.e., 5′ to) a native splice site sequence and downstream from (i.e., 3′ to) a native branch point sequence. The native splice site sequence and the native branch point sequence may serve as members of both the native set of splice site sequences and the aberrant set of splice site sequences.

In some embodiments, a native splice element (e.g., a branch point) is also a member of the set of aberrant splice elements. For example, SMSMs provided herein can block the native element and activate a cryptic element (e.g., a cryptic 5′ss, a cryptic 3′ss or a cryptic branch point), which may recruit remaining members of the native set of splice elements to promote correct splicing over incorrect splicing. In some embodiments, an activated cryptic splice element is in an intron. In some embodiments, an activated cryptic splice element is in an exon. The compounds and methods provided herein can be used to block or activate a variety of different splice elements, depending on the type of aberrant splice element (e.g., mutated splice element or non-mutated splice element) and/or depending on regulation of a splice element (e.g., regulation by upstream signaling pathways). For example, the compounds and methods provided herein can block a mutated element, a non-mutated element, a cryptic element, or a native element; it may block a 5′ splice site, a 3′ splice site, or a branch point.

In some embodiments, an alternate splicing event can be modulated by employing the compounds provided herein. For example, a compound provided herein can be introduced into a cell in which a gene is present that encodes a pre-mRNA that comprises alternate splice sites. In some embodiments, in the absence of the compound, a first splicing event occurs to produce a gene product having a particular function. For example, in the presence of the compound provided herein, the first splicing event can be inhibited. In some embodiments, in the presence of the compound provided herein, the first splicing event can be inhibited and a second or alternate splicing event occurs, resulting in expression of the same gene to produce a gene product having a different function.

In some embodiments, a first inhibited splicing event (e.g., a splicing event inhibited by a mutation, a mutation-induced bulge or a non-mutation induced bulge), is promoted or enhanced in the presence of a compound provided herein. In some embodiments, the first inhibited splicing event (e.g., a splicing event inhibited by a mutation, a mutation-induced bulge or a non-mutation induced bulge), is promoted or enhanced in the presence of a compound provided herein. For example, the inhibition of the first splicing event (e.g., a splicing event inhibited by a mutation, a mutation-induced bulge or a non-mutation induced bulge) can be restored to a corresponding first splicing event that is uninhibited, in the presence of a compound provided herein; or the inhibition of the first splicing event can be decreased, in the presence of a compound provided herein. In some embodiments, a second or alternate splicing event occurs, resulting in expression of the same gene to produce a gene product having a different function.

In some embodiments, the SMSM compounds and methods of their use described herein can modulate splicing, such as alternative splicing of a polynucleotide encoded by MAPT gene. In some embodiments, alternative splicing of the MAPT pre-mRNA may lead to the expression of 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 isoforms of the tau protein. In some embodiments, alternative splicing of the MAPT pre-mRNA may lead to the expression of 6 isoforms of the tau protein. In some embodiments, the 6 isoforms of tau include 3 four-repeat (4R) isoforms and 3 three-repeat (3R) isoforms of the tau protein. In the 3R tau isoforms exon 10 is excluded from the splice variants. For example, a 3R tau isoform in which exon 10 is excluded may include exon 2 and/or exon 3. In the 4R tau isoforms exon 10 is included in the splice variants. For example, a 4R tau isoform in which exon 10 is included may include exon 2 and/or exon 3. The inclusion or exclusion of exon 10 may depend on alternative splicing events in a stem loop occurring at the exon 10 intron 10 junction. In some embodiments, a mutation occurring at the 5′ss results in inclusion of exon 10 in an mRNA encoding the tau protein. In some embodiments, a mutation in an ISS region of the stem loop results in exclusion of exon 10 from the mRNA encoding the tau protein. In some embodiments, a mutation at the 5′ss destabilizes the stem loop, thereby decreasing exon 10 inclusion in the mRNA of tau. In some embodiments, a mutation at the 5′ss inhibits binding of a spliceosome component to the pre-mRNA, thereby decreasing exon 10 inclusion in the mRNA of tau. In some embodiments, a mutation at the ISS region of the stem loop inhibits binding of a spliceosome component to the pre-mRNA, thereby increasing exon 10 inclusion in the mRNA of tau.

In some aspects, the SMSM compounds are used to modulate alternative splicing of tau pre-mRNA. In some embodiments, the SMSM compound binds to the stem loop of exon 10 of the tau pre-mRNA, reducing binding affinity of a spliceosome component to the 5′ss, thereby increasing exclusion of exon 10 in the mRNA of tau and increasing the ratio of 3R:4R tau isoforms. In some embodiments, the SMSM compound binds to the stem loop of exon 10 of the tau pre-mRNA, increasing binding affinity of a spliceosome component to the 5′ss, thereby increasing inclusion of exon 10 in the mRNA of tau and decreasing the ratio of 3R:4R tau isoforms. In some embodiments, the SMSM compound binds to the stem loop of exon 10 of the tau pre-mRNA, reducing binding affinity of a spliceosome component to the ISS region, thereby increasing inclusion of exon 10 in the mRNA of tau and decreasing the ratio of 3R:4R tau isoforms. In some embodiments, the SMSM compound binds to the stem loop of exon 10 of the tau pre-mRNA, increasing binding affinity of a spliceosome component to the ISS region, thereby reducing inclusion of exon 10 in the mRNA of tau and increasing the ratio of 3R:4R tau isoforms.

In some embodiments, the SMSM compound alters the ratio from 3R<4R to 4R<3R. In some embodiments, the SMSM compound binds to the stem loop of exon 10 of the tau pre-mRNA, increasing the thermodynamic stability of the stem loop, thereby reducing inclusion of exon 10 in the mRNA of tau and increasing the ratio of 3R:4R tau isoforms. In some embodiments, the SMSM compound binds to the stem loop of exon 10 of the tau pre-mRNA, decreasing the thermodynamic stability of the stem loop, thereby increasing inclusion of exon 10 in the mRNA of tau and decreasing the ratio of 3R:4R tau isoforms.

SMSMs suitable for injectable use include sterile aqueous solutions (where water soluble) or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion. For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, Cremophor EL™ (BASF, Parsippany, N.J.) or phosphate buffered saline (PBS). In all cases, the composition must be sterile and should be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against contamination from microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, and the like), and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as manitol, sorbitol, sodium chloride in the composition. Dosing and Schedules

The SMSMs utilized in the methods of the invention can be, e.g., administered at dosages that may be varied depending upon the requirements of the subject the severity of the condition being treated and/or imaged, and/or the SMSM being employed. For example, dosages can be empirically determined considering the type and stage of disease diagnosed in a particular subject and/or the type of imaging modality being used in conjunction with the SMSMs. The dose administered to a subject, in the context of the present invention should be sufficient to affect a beneficial diagnostic or therapeutic response in the subject. The size of the dose also can be determined by the existence, nature, and extent of any adverse side-effects that accompany the administration of a SMSM in a particular subject.

It is advantageous to formulate compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms of the invention are dictated by and directly dependent on the unique characteristics of the active compound and the particular therapeutic effect to be achieved, and the limitations inherent in the art of compounding such an active compound for the treatment of individuals. Toxicity and therapeutic efficacy of such compounds can be determined by procedures in cell cultures or experimental animals, e.g., for determining the LD₅₀ (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio LD₅₀/ED₅₀. Compounds that exhibit large therapeutic indices are preferred. While compounds that exhibit toxic side effects may be used, care should be taken to design a delivery system that targets such compounds to the site of affected tissue to minimize potential damage to uninfected cells and, thereby, reduce side effects.

Therapeutic index data obtained from cell culture assays and/or animal studies can be used in predicting the therapeutic index in vivo and formulating a range of dosages for use in subjects, such as human subjects. The data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. For any compound used in the method of the invention, the therapeutically effective dose can be estimated initially from cell culture assays. A dose may be formulated in animal models to achieve a circulating plasma concentration range that includes the concentration of the test compound which achieves a half-maximal inhibition of symptoms as determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Levels in plasma may be measured, for example, by high performance liquid chromatography. Various animal models and clinical assays for evaluating effectiveness of a particular SMSM in preventing or reducing a disease or condition are known in the art may be used in the present invention. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. The exact formulation, route of administration and dosage can be chosen by the individual physician in view of the patient's condition.

Assays

Gene expression experiments often involve measuring the relative amount of gene expression products, such as mRNA, expressed in two or more experimental conditions. This is because altered levels of a specific sequence of a gene expression product can suggest a changed need for the protein coded for by the gene expression product, perhaps indicating a homeostatic response or a pathological condition.

In some embodiments, a method can comprise measuring, assaying or obtaining expression levels of one or more genes. In some cases, the method provides a number or a range of numbers, of genes that the expression levels of the genes can be used to diagnose, characterize or categorize a biological sample. In some embodiments, the gene expression data corresponds to data of an expression level of one or more biomarkers that are related to a disease or condition. The number of genes used can be between about 1 and about 500; for example about 1-500, 1-400, 1-300, 1-200, 1-100, 1-50, 1-25, 1-10, 10-500, 10-400, 10-300, 10-200, 10-100, 10-50, 10-25, 25-500, 25-400, 25-300, 25-200, 25-100, 25-50, 50-500, 50-400, 50-300, 50-200, 50-100, 100-500, 100-400, 100-300, 100-200, 200-500, 200-400, 200-300, 300-500, 300-400, 400-500, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, 500, or any included range or integer. For example, at least about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 33, 35, 38, 40, 43, 45, 48, 50, 53, 58, 63, 65, 68, 100, 120, 140, 142, 145, 147, 150, 152, 157, 160, 162, 167, 175, 180, 185, 190, 195, 200, 300, 400, 500 or more total genes can be used. The number of genes used can be less than or equal to about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 33, 35, 38, 40, 43, 45, 48, 50, 53, 58, 63, 65, 68, 100, 120, 140, 142, 145, 147, 150, 152, 157, 160, 162, 167, 175, 180, 185, 190, 195, 200, 300, 400, 500, or more.

In some embodiments, relative gene expression, as compared to normal cells and/or tissues of the same organ, can be determined by measuring the relative rates of transcription of RNA, such as by production of corresponding cDNAs and then analyzing the resulting DNA using probes developed from the gene sequences as corresponding to a genetic marker. Thus, the levels of cDNA produced by use of reverse transcriptase with the full RNA complement of a cell suspected of being cancerous produces a corresponding amount of cDNA that can then be amplified using polymerase chain reaction, or some other means, such as linear amplification, isothermal amplification, NASB, or rolling circle amplification, to determine the relative levels of resulting cDNA and, thereby, the relative levels of gene expression. General methods for determining gene expression product levels are known to the art and may include but are not limited to one or more of the following: additional cytological assays, assays for specific proteins or enzyme activities, assays for specific expression products including protein or RNA or specific RNA splice variants, in situ hybridization, whole or partial genome expression analysis, microarray hybridization assays, SAGE, enzyme linked immuno-absorbance assays, mass-spectrometry, immuno-histochemistry, blotting, microarray, RT-PCR, quantitative PCR, sequencing, RNA sequencing, DNA sequencing (e.g., sequencing of cDNA obtained from RNA); Next-Gen sequencing, nanopore sequencing, pyrosequencing, or Nanostring sequencing. Gene expression product levels may be normalized to an internal standard such as total mRNA or the expression level of a particular gene including but not limited to glyceraldehyde 3-phosphate dehydrogenase, or tubulin.

Gene expression data generally comprises the measurement of the activity (or the expression) of a plurality of genes, to create a picture of cellular function. Gene expression data can be used, for example, to distinguish between cells that are actively dividing, or to show how the cells react to a particular treatment. Microarray technology can be used to measure the relative activity of previously identified target genes and other expressed sequences. Sequence based techniques, like serial analysis of gene expression (SAGE, SuperSAGE) are also used for assaying, measuring or obtaining gene expression data. SuperSAGE is especially accurate and can measure any active gene, not just a predefined set. In an RNA, mRNA or gene expression profiling microarray, the expression levels of thousands of genes can be simultaneously monitored to study the effects of certain treatments, diseases, and developmental stages on gene expression.

In accordance with the foregoing, the expression level of a gene, marker, gene expression product, mRNA, pre-mRNA, or a combination thereof may be determined using northern blotting and employing the sequences as identified herein to develop probes for this purpose. Such probes may be composed of DNA or RNA or synthetic nucleotides or a combination of these and may advantageously be comprised of a contiguous stretch of nucleotide residues matching, or complementary to, a sequence corresponding to a genetic marker identified in FIG. 4. Such probes will most usefully comprise a contiguous stretch of at least 15-200 residues or more including 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 80, 85, 90, 95, 100, 110, 120, 130, 140, 150, 160, 175, or 200 nucleotides or more. Thus, where a single probe binds multiple times to the transcriptome of experimental cells, whereas binding of the same probe to a similar amount of transcriptome derived from the genome of control cells of the same organ or tissue results in observably more or less binding, this is indicative of differential expression of a gene, marker, gene expression product, mRNA, or pre-mRNA comprising, or corresponding to, sequences corresponding to a genetic marker from which the probe sequence was derived.

In some embodiments of the present invention, gene expression may be determined by microarray analysis using, for example, Affymetrix arrays, cDNA microarrays, oligonucleotide microarrays, spotted microarrays, or other microarray products from Biorad, Agilent, or Eppendorf. Microarrays provide particular advantages because they may contain a large number of genes or alternative splice variants that may be assayed in a single experiment. In some cases, the microarray device may contain the entire human genome or transcriptome or a substantial fraction thereof allowing a comprehensive evaluation of gene expression patterns, genomic sequence, or alternative splicing. Markers may be found using standard molecular biology and microarray analysis techniques as described in Sambrook Molecular Cloning a Laboratory Manual 2001 and Baldi, P., and Hatfield, W. G., DNA Microarrays and Gene Expression 2002.

Microarray analysis generally begins with extracting and purifying nucleic acid from a biological sample, (e.g. a biopsy or fine needle aspirate) using methods known to the art. For expression and alternative splicing analysis it may be advantageous to extract and/or purify RNA from DNA. It may further be advantageous to extract and/or purify mRNA from other forms of RNA such as tRNA and rRNA. In some embodiments, RNA samples with RIN≤5.0 are typically not used for multi-gene microarray analysis, and may instead be used only for single-gene RT-PCR and/or TaqMan assays. Microarray, RT-PCR and TaqMan assays are standard molecular techniques well known in the relevant art. TaqMan probe-based assays are widely used in real-time PCR including gene expression assays, DNA quantification and SNP genotyping.

Various kits can be used for the amplification of nucleic acid and probe generation of the subject methods. In some embodiments, Ambion WT-expression kit can be used. Ambion WT-expression kit allows amplification of total RNA directly without a separate ribosomal RNA (rRNA) depletion step. With the Ambion® WT Expression Kit, samples as small as 50 ng of total RNA can be analyzed on Affymetrix® GeneChip® Human, Mouse, and Rat Exon and Gene 1.0 ST Arrays. In addition to the lower input RNA requirement and high concordance between the Affymetrix® method and TaqMan® real-time PCR data, the Ambion® WT Expression Kit provides a significant increase in sensitivity. For example, a greater number of probe sets detected above background can be obtained at the exon level with the Ambion® WT Expression Kit as a result of an increased signal-to-noise ratio. Ambion WT-expression kit may be used in combination with additional Affymetrix labeling kit.

In some embodiments, AmpTec Trinucleotide Nano mRNA Amplification kit (6299-A15) can be used in the subject methods. The ExpressArt® TRinucleotide mRNA amplification Nano kit is suitable for a wide range, from 1 ng to 700 ng of input total RNA. According to the amount of input total RNA and the required yields of a RNA, it can be used for 1-round (input >300 ng total RNA) or 2-rounds (minimal input amount 1 ng total RNA), with a RNA yields in the range of >10 μg. AmpTec's proprietary TRinucleotide priming technology results in preferential amplification of mRNAs (independent of the universal eukaryotic 3′-poly(A)-sequence), combined with selection against rRNAs. This kit can be used in combination with cDNA conversion kit and Affymetrix labeling kit.

In some embodiments, gene expression levels can be obtained or measured in an individual without first obtaining a sample. For example, gene expression levels may be determined in vivo, that is in the individual. Methods for determining gene expression levels in vivo are known to the art and include imaging techniques such as CAT, MRI; NMR; PET; and optical, fluorescence, or biophotonic imaging of protein or RNA levels using antibodies or molecular beacons. Such methods are described in US 2008/0044824, US 2008/0131892, herein incorporated by reference. Additional methods for in vivo molecular profiling are contemplated to be within the scope of the present invention.

On the day of the experiment, a 96-well plate was seeded with the cell lines of interest. The cells were diluted with full growth media to a concentration of 2.0×10⁵ cells/mL and 100 μL of cells were added to each well (20,000 cells per well). The cells were treated with a compound immediately after plating.

The compounds were then added to the cell plate using the HP compound dispenser. In the initial experiment, a top concentration of 10 μM and an 8 point 4-fold dilution scheme was used. The stock compounds were made at a concentration of 5 mM, and the DMSO concentration was set to 0.2%. DMSO was used to normalize all the compound-containing wells and the untreated cells.

The treated cells were incubated at 37° C. in a 5% CO₂ incubator for the desired amount of time. Plates were placed in a plastic bag with a wet paper towel to prevent evaporation.

RNA was isolated using the Cells to C_(T) kit (ThermoFisher, AM1728). The cells were washed once with 100 μL cold PBS. 50 μL of lysis buffer was added to each well/tube (49.5 μL lysis buffer+0.5 μL DNase I per well/tube). The lysis reaction was mixed and incubated at room temperature for 5 minutes. 5 μL of stop solution was added directly into each cell lysis reactionand mixed by pipetting up and down 5 times. The plates/tubes were incubated at room temperature for 2 minutes then placed on ice if the cDNA synthesis was to be performed immediately. Otherwise, the plates/tubes were stored at −80° C. cDNA synthesis reactions were then performed. Reverse Transcription (RT) Master mix was prepared according to the table below.

The G Blocks were inserted into the pCI-neo mammalian expression vector (Promega) at the EcoRI and NotI restriction sites (bolded) using Infusion cloning technology (Clontech). The plasmids were then purified using standard miniprep or maxiprep kits (Macherey Nagel).

Standard Curve Preparation

The dilution necessary to make the top standard is calculated. A top concentration 200,000,000 copies/μL of the stock plasmid was prepared in TE buffer. A series of 10-fold dilutions, also in TE, were then made. A total of 5 μL of each standard was used in a qPCR well to generate samples containing 10⁹ copies, 10⁸ copies, 10⁷ copies, 10⁶ copies, 10⁵ copies, 10⁴ copies, 10³ copies, 10² copies, 10¹ copies, and 0 copies.

An assay to measure the FOXM1^(A2) mRNA and FOXM1^(BC) mRNA, or MADD^(WT (isoform 4)) mRNA and MADD^(Ex16 (isoform 3)) mRNA, or MAPTau^(4R) mRNA and MAPTau^(3R) mRNA simultaneously in cell wells was performed. The RNA values were measured relative to DMSO control and also included a housekeeping gene, PPIA to ensure data was consistent. The mRNA values were measured after 24 hours of incubation with the SMSM compounds. The SMSMs dose dependently increased FOXM1^(A2) levels while concomitantly decreasing FOXM1^(BC) levels with EC₅₀ and IC₅₀ values in the nanomolar range. This assay was performed in the cell lines shown in Table 3A. Exemplary FOXM1 results are shown in Table 3A.

Protocol

On the day of the experiment, a 96-well plate was seeded with the cell lines of interest. The cells were diluted with full growth media to a concentration of 2.0×10⁵ cells/mL and 100 μL of cells were added to each well (20,000 cells per well). The cells were treated with a compound immediately after plating.

The compounds were then added to the cell plate using the HP compound dispenser. In the initial experiment, a top concentration of 10 μM and an 8 point 4-fold dilution scheme was used. The stock compounds were made at a concentration of 5 mM, and the DMSO concentration was set to 0.2%. DMSO was used to normalize all the compound-containing wells and the untreated cells.

The treated cells were incubatedat 37° C. in a 5% CO₂ incubator for the desired amount of time. Plates were placed in a plastic bag with a wet paper towel to prevent evaporation.

RNA was isolated using the Cells to C_(T) kit (ThermoFisher, AM1728). The cells were washed once with 100 μL cold PBS. 50 μL of lysis buffer was added to each well/tube (49.5 μL lysis buffer+0.5 μL DNase I per well/tube). The lysis reaction was mixed and incubated at room temperature for 5 minutes. 5 μL of stop solution was added directly into each cell lysis reactionand mixed by pipetting up and down 5 times. The plates/tubes were incubated at room temperature for 2 minutes then placed on ice if the cDNA synthesis was to be performed immediately. Otherwise, the plates/tubes were stored at −80° C.

cDNA synthesis reactions were then performed. 40 μL RT master mix was added to PCR tubes or plate wells. 10 μL of RNA was added to each tube/well. The RT thermal cycler program was then run and tubes or plate wells were incubated at 37° C. for 1 hour, then at 95° C. for 5 minutes to deactivate the enzyme.

The qPCR was performed using a QuantStudio 6 instrument (ThermoFisher) and the following cycling conditions and according to the tables below. All samples and standards were analyzed in triplicate. Cycle 1: 2 minutes at 50° C. Cycle 2: 10 minutes at 95° C. Cycle 3 (repeat 40 times): 15 seconds at 95° C., 1 minute at 60° C.

Additionally, to monitorexpression levels of SMN2 splice variant using real-time quantitative PCR, SMA type I patient cells (GM03813 (Coriell)) were plated at 5,000 cells/well in 200 μl Dulbecco's modified Eagle's medium (DMEM) with GlutaMAX and 10% fetal bovine serum (FBS) (Life Technologies, Inc.) in 96-well plates, and incubated for 6 hours in a cell culture incubator. Cells were then treated with SMSMs at different concentrations (0.5% DMSO) in duplicate for 24 hours. After removal of the supernatant, cells were lysed in Cells-To-Ct lysis buffer (Life Technologies, Inc.) according to the manufacturer's recommendations. The mRNA levels of SMN2 FL, SMN2 Δ7 were quantified using Taqman-based RT-qPCR and SMN2-specific primers and probes. The SMN2 forward and reverse primers were each used at a final concentration of 0.4 μM. The SMN2 probe was used at a final concentration of 0.15 μM. RT-qPCR was carried out at the following temperatures for indicated times: Step 1: 48° C. (15 min); Step 2: 95° C. (10 min); Step 3: 95° C. (15 sec); Step 4: 60° C. (1 min); Steps 3 and 4 were repeated for 40 cycles. The Ct values for each mRNA were converted to mRNA abundance using actual PCR efficiencies.

Example 16: Cell Viability and Proliferation

Small molecule splicing modulators were tested in a dose-response assay using different cancer cell lines. Cells were first plated in 96-well plastic tissue culture plates (10,000 cells per well). The cells were treated with 500 nM of SMSM or vehicle alone (DMSO) for 48 hours. Following treatment, the cells were washed with PBS, stained with a crystal violet staining solution, and allowed to dry for 48-72 hrs. After drying, sodium citrate buffer was added to each well and allowed to incubate for 5 min at room temperature. The absorbance was measured at 450 nM using a microplate reader (Biorad; Hercules, Calif.). The relative cell proliferation for each of the cancer cell lines was determined.

To measure cell viability, cells were plated in 96-well plastic tissue culture plates at a density of 5×10³ cells/well. Twenty-four hours after plating, cells were treated with various SMSMs. After 72 hours, the cell culture media were removed and plates were stained with 100 mL/well of a solution containing 0.5% crystal violet and 25% methanol, rinsed with deionized water, dried overnight, and resuspended in 100 mL citrate buffer (0.1 M sodium citrate in 50% ethanol) to assess plating efficiency. Intensity of crystal violet staining, assessed at 570 nm and quantified using a Vmax Kinetic Microplate Reader and Softmax software (Molecular Devices Corp., Menlo Park, Calif.), were directly proportional to cell number. Data were normalized to vehicle-treated cells and were presented as the mean±SE from representative experiments. SMSMs that are effective were determined for various cells lines.

Small molecule splicing modulators were tested in a dose-response assay using A673 cells and NHDF cells.

A673 cells or NHDF cells were first plated in 96-well plastic tissue culture plates (10,000 cells per well). The cells were treated with vehicle alone (DMSO), or increasing concentrations of SMSM compounds for 72 h. Following treatment, cell proliferation was determined using a crystal violet assay. The relative cell proliferation at each concentration was determined.

Exemplary results are shown in the table below and FIGS. 9A-9H.

Example 17: Monitoring Expression Levels of FOXM1 Splice Variants Using Real-Time Quantitative PCR

Human fibroblasts were plated at 10,000 cells/well in 200 μL DMEM with GlutaMAX and 10% FBS in 96-well plates in a cell culture incubator (37° C., 5% CO₂, 100% relative humidity). Cells were then treated with SMSMs in Table 1B at different concentrations (0.1-1000 nM, each in 0.5% DMSO) in triplicate for 24 hours. RNA extraction was performed as per instructions in the Cells-to-CT™ Kits (Ambion®, Applied Biosystems). RNA samples were frozen at −20 OC until further analysis. Relative expression levels of full-length FOXM1 (FOXM1^(FL)) or FOXM1 lacking exon VIIa (FOXM1^(ΔVIIa)) with GAPDH for internal control, was measured using one-step multiplex reverse transcription-polymerase chain reaction (RT-PCR). TaqMan® FAM probes were used for relative quantitation of FOXM1^(FL) or FOXM1^(ΔVIIa) expression levels and TaqMan® VIC probes were used for relative quantitation of human GAPDH levels. The fidelity of the amplification methods was determined using the AACt relative quantification method for quantitative PCR. The data shows that the compounds induced alternative splicing of FOXM1 towards full-length FOXM1. The SMSMs increased expression of the FOXM1^(FL) mRNA. Correspondingly, the mRNAs for FOXM1^(ΔVIIa) declined. The data demonstrate that upregulation of FOXM1^(FL) with downregulation of FOXM1^(ΔVIIa) by treatment with the SMSMs of the present disclosure were directly correlated, indicating an effect of the SMSMs on alternative splicing of FOXM1. The resulting concentration dependence curves of the FOXM1^(ΔVIIa) splice variant are fitted to a Hill binding equation to yield IC₅₀ values. Taken together, the data underline a splicing modifying activity in the FOXM1 gene. This may result in arrest of cell cycle and induction of apoptosis, as the FOXM1^(L) variant created by SMSM treatment is functionally inactive, and antagonizes the pro-proliferating. effect of functional FOXM1. Exemplary results are shown in FIG. 7 and FIG. 12.

Female NCrNu mice were used. Age range of enrolment was 7-10 weeks. A total of 75 animals were for the studies.

The A673 tumor cell line was maintained in vitro as a monolayer culture. The tumor cells were routinely subcultured twice weekly by TryplE, and did not to exceed 4-5 passages. The cells growing in an exponential growth phase were harvested and counted for tumor inoculation.

Each mouse were inoculated into a right flank with the single cell suspension of 95% viable tumor cells (5×10⁶ cells/mouse) in serum-free RPMI 1640 Media for tumor development. Treatments were administered when mean tumor size reached approximately 75 mm³.

An acclimation period of a minimum of 72 hrs was allowed between animal receipt and tumor inoculation in order to accustom the animals to the laboratory environment. Immunodeficient NCrNu mice were maintained in a pathogen-free environment. Animals were fed a diet of Irradiated Mouse pellet feed Purina rodent diet #5053 (Fisher Feeds, Bound Brook, N.J.) and chlorinated water from a reverse osmosis (RO) system (4-6 ppm).

Before commencement of treatment, all animals were weighed and assigned to treatment groups using a randomization procedure. Mice were randomized into groups based upon their tumor sizes to ensure that each group had approximately the same mean tumor size and range of tumor size.

After inoculation, the animals were checked daily for morbidity and mortality. At the time of routine monitoring, the animals were checked for any effects of tumor growth on normal behavior such as mobility, food and water consumption, body weight gain/loss, eye/hair matting and any other abnormal effects. Deaths and observed clinical signs were recorded. Animals that were observed to be in a continuing deteriorating condition or bearing a tumor exceeding 2,000 mm³ in size were euthanized.

Body weight were measured prior to tumor inoculation and prior to the treatment administration and then daily. Tumor size were measured 2-3 times per week in two dimensions using a caliper, and the volume were expressed in mm³ using the formula: V=0.5×a×b² where a and b are the long and short diameters of the tumor, respectively.

Studies were terminated when the tumor size in the vehicle treated group reached 2,000 mm³. Each mouse was bled at 2 hrs after the last dose and at least 50 μl of plasma were collected from each mouse. All of the collected plasma samples and retainer dosing solutions for each dose level were used for bioanalytical measurements. All tumors were also collected and weighed. One necrosis-free tumor fragment of approximately 50 mg was taken from each tumor and flash-frozen for RNA isolation. The remaining tumor was flash frozen for PK analysis.
